Rejuven8 Peptides
Very GoodLast updated September 1, 2026
Rejuven8's certificate library is one of the better-organized archives. For metabolic and GLP products it states that each batch is verified by HPLC and mass spectrometry for purity, identity and net peptide content, with a lot-specific COA.
Documented strengths
- ✓Multiple current and historical GLP-2 TZ and GLP-3 RT reports published together.
- ✓Net peptide content reported alongside purity.
- ✓Current TB-500 10 mg documentation includes separate contamination results.
Limitations in this review
- —BPC-157 5 mg and 10 mg have current HPLC/MS lot reports, but the archive does not display the same PCR/endotoxin pair beside those BPC lots.
- —Rank the vendor well overall without implying that every product receives every contamination screen.
